る。Effects of the invention As explained above, when the lock piece is moved in one direction along the side wall, the end face of the latch piece engages with the retaining step formed on the outer surface of the male connector block fitting part, and the male connector block is locked. It is possible to form a locked state that prevents the latch from being removed, and when the lock piece is moved in the other direction along the side wall, the end face of the latch piece comes off the stopper step and the latch connected to one end of the stopper step. It can reach into the single guide groove and form an unlocked state. In the unlocked position, the male connector block can be easily removed from the latch piece using the latch piece guide groove as a guide.

ある。 As already mentioned, in the male and female connectors of the above-mentioned fitting type, if a conventional snap-engaged elastic locking piece is used, the locking mechanism does not take up much space and can have a simple structure. However, there are disadvantages in that it is not easy to release the snap engagement, it takes time to remove the male connector block, and the lock piece loses its function due to reduced elasticity for engagement. Further, when a flange equipped with a locking device is provided, it is possible to form a more robust locking device different from the above-mentioned snap locking device, but there is a drawback that the connector block becomes larger.

ことができる効果がある。 The present invention eliminates the above-mentioned drawbacks, allows the formation of a locking device without increasing the size of the connector block in the longitudinal and lateral width directions, and allows easy locking and unlocking by simply sliding the lock piece. In addition to ensuring reliable locking, the latch piece of the locking piece is folded back in the opposite direction to the direction in which the male connector block is removed and is brought into contact with a retaining step formed on the outer surface of the male connector block fitting part to form the above-mentioned locked state. Therefore, even if the lock piece is made from a relatively thin flat plate, the lock can be strongly maintained without causing deformation or the like.
